Source of material
An amount of 1.38 g of 6-aminopyridine-2-carboxylic acid (10 mmol) was dissolved in 10 mL 45% hydroiodic acid, then filtered. Many red crystals were harvested after about 10 days, yield 74% (based on 6-aminopyridine-2-carboxylic acid).
Experimentaldetails
The structure was solved by direct methods with the SHELXS program. All H-atoms from C and N atoms were positioned with idealized geometry (Uiso(H) = 1.2Ueq(C) and (N)) using a riding model with C–H = 0.95 Å and N–H = 0.88 Å. The H-atoms for O and O1W were refined with the distance of O1–H1A = 0.84, O1–H1WA = O1–H1WB = 0.87 Å with Uiso(H) = 1.5Ueq(O), respectively.
Comment
Many pyridinium-based polyiodides have been reported, for example, 2-amino-pyridin-1-ium triiodide [5, 6] and bis((4-aminopyridin-1-ium) iodide triiodide. But only a few pyridinium-based pentaiodides have been published, such as aminopyridinium pentaiodide [7], isoquinolinium pentaiodide [8], nevirapinium pentaiodide [9], N-(6-methyl-2-pyridyl)mesitylenesulfonamide pentaiodide [10], and 3-[5-(pyridin-3-yl)-1,2,4-thiadiazol-3-yl]pyridinium pentaiodide [11].
The title compound, with the formula of C6H9I5N2O3, crystalizes in triclinic, P-1 (no. 2). The asymmetric unit is made of one 6-amino-5-carboxypyridin-1-ium cation, one pentaiodide anion and one water molecule. In the 6-amino-5-carboxypyridin-1-ium cation, the N atom from of the pyridine ring is protonated and both the amino and carboxyl groups are neutral. The distances of I4–I5 and I2–I3 are 2.794 and 2.760 Å, respectively, rather shorter than the distances of I1–I5 (3.101 Å) and I1–I2 (3.181 Å). The structure features an organic moiety consisting of two water molecules and two cations to form the dimers, which are generated by the hydrogen bonds N1–H1⋯O2, N2–H2A⋯O2, and O1–H1A⋯O1W. The anions and the cations are connected by van der Waals interactions to form layers in the bc plane.
